FURNACE ATTACHMENT. l

SPECIFICATION forming part of Letters Patent No.,469,877, dated March 1,1892'.

Application led November 7, 1391l Serial No. 411,150. (No model.)

To all whom-t may concern:

Be it known that I, EDWARD WAUGH, of Brooklyn, in the county of Kingsand State of New York, have invented a new and useful Improvement inFurnace Attachments, of

represented in the accompanying drawings,

in which- Figure l represents a furnace in longitudinal verticalsection, showing the attachment in position for use; and Fig. 2represents a View of the attachment in detail, showing a modified formof support.

A represents the furnace-wall, and B the grate, the latter shown in thepresent instance as consisting of a double set of grate-bars resting attheir adjacent edges upon a common support 'b and at their oppositeedges upon lugs at the front and bridge walls of the furnace.

C represents the opening for feeding the fuel to the furnace, and c theopening leading to the ash-pit D beneath the grate.

The attachment consists ofa sheet or plate E, of metal or other suitablematerial, adapted to rest with its front or lower end at the bottom ofthe ash-pit7 preferably at the entrance c, and with its rear or upperend in proximity to the under side of the grate B, the said sheetextending transversely across the'ash-pit from side to side andseparating it substantially into two chambers, the one in connectionwith the draft-opening and front and central portions of the grate andthe latforth.

the lower ends of said standard resting upon the vfloor of the ash-pit.When the standards e are employed, I prefer to secure them pivotally tothe plate E in order that the rear end of the said plate may be elevatedor depressed at pleasure by the swinging of the standard e into or awayfrom a vertical position. The opening c, through which the air isadmitted to the under side of the grate,`is provided with a damper c. ofany well-known or approved construction, which may be elevated ordepressed at different intervals to admit more or less air to theash-pit above the plate E, as may be required. In the present instancethe damper is shown as provided with lugs c2, on which the front end ofthe plate E rests.

I have found in'actual practice that the above-described attachment whenapplied in the manner substantially as shown in Fig. l to a furnace ofordinary construction has increased the heating capacity of the furnacefrom eighteen per cent. to thirty per cent. Without increasing theamount of fuel fed to the furnace.

The attachment is exceedingly simple and inexpensive and may readily beattached to furnaces in common use, either by the bolts e or by the.supporting-standards e', as may be found most expedient. It will beobvious that the rear end of the plate e may be elevated or depressed toadjust it nearer to or farther from the grate either by the nut on thelower end of the bolt or by the swinging of the standard e.

What I claim is- The herein-described furnace attachment, comprising aplate adapt-ed to extend from the draftopening at the front of theash-pit upwardly and rearwardly to a point in proximity to the underside of the grate and means for sustaining the rear end of the plate invertical adjustment toward and away from the under side of the grate,substantially as set `EDWARD WAUGII.
